Pavel Durov, the Russian-born billionaire founder and owner of the Telegram messaging app, was arrested at Le Bourget airport outside Paris shortly after landing on a private jet late on Saturday and placed in custody, three sources told Reuters.
The arrest of the 39-year-old technology billionaire prompted on Sunday a warning from Moscow to Paris that he should be accorded his rights and criticism from X owner Elon Musk who said that free speech in Europe was under attack.
